- This week's traffic impacts
- Lynn Point Road, which intersects with US 101 just south of the Middle Nemah River Bridge, has been realigned to create a safer connection with the highway.
- Traffic has been shifted to a single-lane, detour bridge, and the speed limit temporarly reduced to 25 mph through the project area. Expect delays during weekend and holiday travels.
This project replaces the existing US 101, Middle Nemah River Bridge (milepost 33.84) with a new 36-foot-wide structure consisting of two 12-foot-wide lanes with six-foot-wide shoulders.
The new bridge will help improve safety and increase mobility on US 101 in Pacific County.
During construction, WSDOT will build a temporary one-lane bridge on the west side of the existing Middle Nemah River Bridge to detour traffic around the work zone.
Why is WSDOT
constructing a new US 101, Middle Nemah River Bridge?
The existing bridge was constructed in 1935 of timber trestles.
The bridge is aging and too narrow to accommodate the types or number of vehicles that need to cross it today. It also does not meet current federal seismic, flood, or structural standards.
WSDOT is replacing the existing structure with a new bridge span built of concrete girders. The new bridge will enhance safety and allow US 101 to remain a viable West Coast freight route.
The End Result
A wider, safer bridge that accommodates today's traffic and meets current federal seismic, flood and structural standards.
- Safety: Improves safety and drivability by constructing a wider roadway, and installing concrete road barriers and new bridge railings.
- Mobility: Provides a wider structure for motorists and allows traffic to flow smoothly across the bridge without delay.
- Environmental: Removes approximately 44 creosote-treated timber piles from Middle Nemah River and restores an estimated 28 square feet of streambed. The project also improves the river channel under US 101.
